Definitions

  • the invention relates to hydraulic anti-vibration devices intended to be interposed for the purpose of damping and connection, or even support, between two rigid elements such as a vehicle chassis and the engine of this vehicle.
  • the periphery of the deformable valve is clamped between two rigid seats integral with the grids, and it is the central zone of this valve which is subject to displacements of greater amplitude, limited displacements by abutment of this central area against the grids.
  • the successive applications of said central zone against the grids generate clicking noises.
  • This formula also has a certain number of drawbacks concerning in particular the risks of punching of the center of the valve by the pins, the importance of the deformations imposed on this valve near the pins, the abrupt applications of the valve against the grids ...
  • the object of the invention is, above all, to remedy these various drawbacks.
  • the anti-vibration devices of the type in question according to the invention also comprise a valve arranged and mounted in such a way that only its central zone is permanently in contact with the two grids and clamped between them and they are essentially characterized in that the surfaces of the two grids, facing the valve are flat and in that said valve. comes in the form of a biconvex lens.
  • the invention includes, apart from this main arrangement, certain other arrangements which are preferably used at the same time and which will be more explicitly discussed below.
  • Figure 1 of this drawing shows in axial section a hydraulic antivibration support established according to the invention.
  • Figure 2 shows in axial section, on a larger scale, the central portion of this support, the valve being shown in its rest position.
  • Figure 3 differs only from Figure 2 in that the valve is shown in one of its two extreme deformed positions.
  • All of the peripheral areas of the flexible bellows 4, of the cover 5 and of the intermediate partition 6 are crimped one against the other by folding the flange 21 included by one of the two plates constituting the ring 2 against the 'other plate, the rim 21 of this other plate being, meanwhile, embedded in the large base of the thick frustoconical wall 3.
  • the invention relates more particularly to valve 8.
  • This valve is made of a deformable material, preferably elastic: it is for example an elastomer, reinforced or not by a suitable fabric.
  • each face being curved with a continuous curvature, advantageously spherical.
  • the valve 8 occupies its middle rest position while in FIG. 3, it is represented in one of its two extreme deformation positions, for which it is applied throughout one of its two transverse faces, then become flat, against the grid 10 opposite: for this position, the valve closes all the orifices of the grid 10 considered so that all communication is interrupted through the grids 9 and 10 between the two chambers A and B.
  • the deformations imposed on the valve by the axial back-and-forth movements of the liquid due to the oscillations or vibrations to be damped have the effect of applying the valve alternately, in an extremely progressive manner, against each of the grids which frame it, like a rollover, and not suddenly apply a whole range at least of this valve against the grid opposite, which reduces or even eliminates the slamming effect and the noise which results therefrom .
